Add Yahoo as a preferred source to see more of our stories on Google. The purported benefits of an infrared sauna offer plenty of promise—from limbering up our limbs to detoxifying our bodies—and the ...

A team has constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low ...

A research team has developed a flexible near-infrared (NIR) photodetector that delivers photoresponsivity more than five ...

Most people can perceive different colours in the visible range of the electromagnetic spectrum – at wavelengths between about 400 and 700 nm. However, our eyes cannot see infrared radiation, let ...

The groundbreaking infrared sensors use layers of repeating molecular structures to interact with individual photons, or units of light. The sensors resolve more wavelengths of infrared at a higher ...

Human vision relies on photoreceptor cells in the retina that react to visible light and trigger neurons in the optic nerve to send signals to the brain. Degradation of these photoreceptors is the ...

Hotter objects typically glow brighter than cooler ones, making them stand out in infrared images. But a newly designed coating bucks the rule that hotter equals brighter. For certain wavelengths of ...

Berly McCoy and Regina Barber of Short Wave talk about a hawk's clever hunting strategy, contacts that allow wearers to see infrared light, and how immunity varies during the day. It's time for our ...
